I tend to agree with roxeen. No professional (Gemologist, Mineralogist,Lapidary etc.) should or for that matter could give an accurate identification based solely on a picture. I could list no less than 15 tests that wold be essential to ID the “green within” that does not include ID of the “black glassy matrix. Beyond the basics XRD X-ray diffraction,microprobe analysis and even mass spectroscopy may be required. A local college with a decent geology department might help, private grops (Excaliberminerals etc.) may be useful but some tests are expensive $100.00+ each, additional info might also be critical such as location.
Good Luck====Rob
